1 Introduction

1-1 Introduction

Thank you for purchasing the AR-ONE Ultra Wide Band Communications receiver.

The AR-ONE is designed using the very latest technology to ensure the highest levels

of

performance and reliability. To get the best possible results from your AR-ONE, we

strongly recommend you to read this manual and familiarize yourself with the receiver.

Although carefully designed, this receiver (like all receivers) suffers from a degree of

internal noises known as spurious emission. They are a product of the receivers

circuitry, and therefore, it does not represent a fault. Apparent faults may be due to

accidental misoperation of the receiver. If you believe there is a problem, carefully read


7/84

6

all of the manual before deciding to contact your dealer for advice.

It is acknowledged that sections of this manual are repetitive, this is to enable themanual to be used as a reference book (you dont have to read it all from cover to cover

in one go). Due to the international nature of the product, some graphics contain

Japanese characters.

Every effort has been made to make this manual correct and up to date. Due to

continuous development of the receiver. and by error or omission anomalies may be

found and this is acknowledged.

This manual is protected by copyright AOR, LTD. 2003. No information contained in

this manual may be copied or transferred by any means without the prior written

consent

of AOR, LTD. AOR and the AOR logo are trademarks of AOR, LTD. All other

1-2 Take care of your radio

There are no internal operator adjustments. In the unlikely event of servicing beingrequired, please contact your dealer for technical assistance.

Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to avoid

locations where excessive heat, humidity, dust and vibration are expected. Always

keep

the AR-ONE free from dust and moisture. Use a soft, dry cloth to gently wipe the set

clean, never use abrasive cleaners or organic solvents which may damage certain

parts.

Treat the AR-ONE with care, avoid spillage or leakage of liquids into the receiver and

associated power supply. Special care should be taken to avoid liquid entering around

the controls, through the speaker grille or via the connection jacks.

The AR-ONE is designed for operation from a good quality regulated DC supply of 12

to

14 V, which should be capable of supplying 1.5 amps. Never connect the AR-ONE

directly to the AC outlet.

The DC input jack is configured Center Positive, the chassis of the receiver is at

negative ground. Where provided (depending upon world market location), the power

supply is pre-wired and provides a nominal 12 V DC output with suitable connectors

being fitted as standard for the AC power input and connection to the AR-ONE.

SAFETY NOTICE Always disconnect the power supply from the AC outlet when

not in use. If used mobile, it should be noted that the AR-ONE has NOT been

manufactured or tested to meet any specific mobile safety requirements.

The AR-ONE has no internally user adjustable parts.

If using the AR-ONE in a base station situation, the best short wave reception is usually

achieved by the fitting of a separate external earth rod, however, consider the

implications carefully if your AC building supply uses a Protective Multiple Earth (PME)

system. If in doubt consult an expert electrician. Never earth to a gas pipe!

The AR-ONE has a single N type antenna connector for all frequencies. This is intended

for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole,


9/84

8

unipole, Yagi, etc. When sighting the antenna, avoid power cables. Ensure that you do

not confuse the antenna and other IF output connectors as they are closely located.

Operating anomalies

Should the AR-ONE appear to behave strangely, normal operation may be easily

achieved by resetting the microprocessor. Two scenarios may be encountered due to

power transients etc:

1. Symptom: LCD remains on, no control of the keypad.

Action: Remove any connection to external power and leave it for

approximately 30 seconds. Reconnect power and switch on again.

Normal operation should be restored but the last used frequency will be lost, the

AR-ONE will restore the last but one frequency to

display.

2. Symptom: The AR-ONE fails to power up.

Action: Try the suggestions given in (1) then hold the ESC key while

powering up the AR-ONE to Soft reset the microprocessor.

1-3 Attention while operating

1. Certain key operation are acted upon when the key is RELEASED, not while it

is pressed. Allow time for the AR-ONE to register such actions before pressing

another key.

2. The keylock (LOCK) is intentionally made to be difficult to operate to prevent

accidental operation. To release keylock, the LOCK key has to be held for more

than one second, the key icon on the LCD confirms operation. The LOCKis

disabled during keying sequences (such as when entering frequencies).

3. If a key sequence is not completed, the microprocessor will automatically

abort

most operations after about 90 seconds of keypad inactivity.

4. Currently displayed VFO data is saved at power down (to increase speed of

operation and to reduce write cycles). For this reason, if the AR-ONE is powered

down using the PWR/VOLcontrol or external power is removed, the last

displayed frequency will be lost and the frequency used prior to this will be

displayed when next powered up.

Terminology Search & Scan


10/84

9

If you have not used a wide band receiver before or not familiar with the terminology used,

itis very important to understand the difference between SEARCHand SCANmodes.

SEARCH: The AR-ONE provides several operations where transmissions (active

frequencies) may be automatically located by sweeping the receiver over a wide

frequency range, either from the currently displayed frequency traveling upwards

(or downwards) in a specified tuning increment (step) or by sweeping

over-and-over between two specified frequency limits. This process is known as

SEARCHING, as the little implies, it can take a long time to find transmissions due

to their often intermittent and brief nature. For this reason it is best to slice large

frequency ranges into smaller, more manageable pieces where they may be

intensively studied.

When examining large frequency bands, it is common to find that 90% of

frequencies are inactive and only a small number of the remaining constitute what

you really want. Searching still remains the best way to initially locate active and

interesting transmissions (in conjunction with a good frequency listing and band

plan).

SCAN: Once active transmission have been identified (either by searching or by

using a good frequency guide), it is more efficient to store the data into memories

which can be rapidly and automatically monitored in succession stopping when

activity is encountered. This forms a much more efficient means of monitoring the

most wanted frequencies as you have targeted 100% what you most want to hear,

by contrast searching is very inefficient for say-to-day monitoring.

Note: It is very important that the squelch is advanced to cancel background

noise for the search & scan functions to operate.This is because the

AR-ONE believes that it has found an active frequency when the squelch

opens and S squelch open icon is displayed to the left of the signal meter.

Advance the squelch control clockwise until the background noise is just

cancelled, this is known as the threshold position. If the squelch control is

advanced too far, weaker signals may be missed.

No noise and no S icon displayed (with squelch advanced clockwise


11/84

10

passed threshold) = squelch closed.

Signal received or noise emanating from speaker (squelch fullycounterclockwise, below threshold) with S icon displayed = squelch open.

terminated in a 9-pin male connector. The RS-232C parameters may be defined using the

CONFIGmenu. Baud rates (transfer speed) set to either 4800 or 9600 bps. Since there are

two independent RS-232C port with the AR-ONE, it is possible to set an address to

facilitate connection of up to 99 AR-ONE to a single PC.

The RS-232C parameters are as follows:

Baud Rate: 4800 or 9600 bps

De-limiter: CR, LF

Data bit: 8 bit

Stop bit: 2 bit

Parity: None

X parameter: ON

1-7 IF output and Spectrum Display Unit (SDU5500, SDU5600 )

The rear panel has a 10.7 MHz IF output designed to drive the optional SDU5500 or

SDU5600 Spectrum Display Unit. The SDU5500 or SDU5600 provides an excellent tool for

locating elusive transmission with a PEAK capability to freeze the briefest of transmissions

for later measurement of frequency and level after the event.

(Note: The IF output frequency is selectable in the CONFIGmenu. (10.7 MHz or 455KHz).

2 Getting started

2-1 Making the AR-ONE ready for operation

2-1-1 LCD (Liquid Crystal Display)

All relevant operational information is provided via the LCD. The LCD contrast is

adjustable.


18/84

17

2-1-2 Connect the antenna

For reception on the all bands, connect the antenna to the N connector on the rear panel ofthe AR-ONE. An optional SA7000 Super Wideband Receiver is provided for this purpose.

A receive frequency range of the SA7000 is 30 KHz ~ 2000 MHz.

2-1-3 Connect power

Connect the power to the DC power jack on the rear panel of the AR-ONE. Use either a

supplied AC power adapter. Or a regulated DC power supply (12 ~ 14 V with capacity 2A)

may be used. Do not connect to a 24 V system.

Main Power Switch ___| |___ DC Power Jack

2-2 Switching On for the first time

Set the squelch control to the mid point . Turn the power switch on the rear panel of the

AR-ONE. This is a main power switch. The Green LED lit on the switch. Then rotate the

PWR/VOL control to the mid point, as you start to rotate the PWR/VOL control, a click will

be heard as the power isolation switch contact switches on. Please be careful NOT to

switch

on any receiver with an earphone connected, there may be an audible click when the unit is

switched on or the volume may be accidentally set too high.

Power/VOL control

Squelch control

The AR-ONE will take approximately 1 - 2 seconds before the information appears on the


19/84

18

LCD. It is normal, for the microprocessor of the AR-ONE generates the boot up data

required to control the receiver.

2-3 Squelch Circuit

In normal use, NOISE SQUELCHis used. However, LEVEL SQUELCHcan be selected for

search and scan operations. The LEVEL SQUELCHparameter causes the AR-ONE to

check the signal strength of activefrequencies and to only stop when the signal strength is

above a preset level (which is programmable).

To select LEVEL SQUELCH, perform the following steps:

1. Push the FUNCkey.

2. Push the 8 key.

3. On the bottom of the LCD, a bar will be displayed. Using the SQL control,

adjust the desired signal level.

4. Push the ENTkey to confirm entry.

5. Squelch will open only when the input signal strength is above this set level.

6. To select NOISE SQUELCH, repeat above steps.

2-4 VFO selection

The AR-ONE has ten (10) VFOs being identified as V-A through V-J on the top left of

the

LCD. The term VFO historically means Variable Frequency Oscillatorand today refers

to

a tuneable data store which contains frequency, step, step-adjust, attenuator etc. Pushing

the VFOkey each time will select the one VFO out of 10. The AR-ONE has an

AUTOMODE setting, and therefore, in most cases a proper receive mode and frequency


20/84

19

step are automatically selected.

2-4-1 Tuning frequency2-4-1-1 Entering a frequency using the numeric keypad

While in VFOmode, enter the required frequency using MHz format followed by the ENT

key.

Example of frequency entry of 80.8 MHz

Push the [8] key. Push the [0] key. Push the [.] key. Push the [8] key. Push the [ENT] key.

Example of frequency entry of 954 KHz (0.954 MHz)

Push the [.] key. Push the [9] key. Push the [5] key. Push the [4] key. Push the [ENT] key.

Aborting frequency input

If for some reason you do not wish to complete the frequency data input, push the ESCkey

before completing the input sequence with the ENT key.

2-4-1-2 Changing frequency using the main tuning dial

While in VFO mode, the active VFO frequency may be tuned in using the rotary main

tuning

dial which is mounted on the right side of the front panel. You may rotate the dial clockwise

to increase frequency or turn counterclockwise to decrease frequency.

2-4-1-3 Changing frequency using UP arrow key or DOWN arrow key

The UP arrow key and DOWN arrow key provide a convenient method of frequency

change.


21/84

20

The speed at which the receiver steps up or down depends upon the STEP SIZEwhich is

default to AUTO. In AUTOthe step size, receiver mode etc. is taken from the factory

pre-programmed band plan but may be overridden at any time.

Push the UParrow key to tune the receiver upward in whichever step size is selected, use

the DOWN arrow key to tune the receiver downward in frequency.

2-5 Changing receive mode

Due to the necessities of signal bandwidth, channel occupancy and transmission efficiency.

Different receive modes are used by various services. In addition to this specification for

tuning step and receive mode are allocated by departments of Governments following

international discussions so are not consistent throughout the world. For this reason, it is

necessary to change receive mode in order to monitor various transmissions.

For your convenience, receive mode and tuning step size have been pre-programmed into

the AR-ONE auto-mode band plan data at the factory to simplify operation of the receiver,

especially while you familiarize yourself with all functions. Should you wish, the defaults

may

be manually overridden at anytime so that you may select an alternative receive mode and

tuning step on any frequency.

AM

Amplitude Modulation Used by broadcast services throughout the world on long wave,

medium wave and shortwave. AM is also used by VHF airband, UHF military airband and

some PMR (Private Mobile Radio) and utility services.

FM

There are two common types of FM (Frequency Modulation, these are:

NFM Narrow Band Frequency Modulation this provides high quality communication for

relatively short distance operation. FM uses a greater frequency bandwidth than other

modes such as SSM so is less efficient.

NFM is the most common mode used above 30 MHz with the exception of the airbands.

NFM is widely used on the VHF bands: VHF marine band, 2m amateur band, 70 cm

amateur band, PMR (Private Mobile Radio) and utilities.


22/84

21

In the absence of signal, the background white noise may appear quite loud. For ease of

listening, the squelch control should be rotated clockwise until he background noise just

disappears, this should be carried out while no signal is present. The point where thebackground noise is cancelled is known as threshold point. Do not advance the squelch

control more than necessary or the receiver will appear to be desensitized and weaker

signals will be missed.

WFM Wide Band Frequency Modulation used by VHF and UHF broadcast stations as

excellent audio quality is available due to the relatively wide frequency bandwidth

employed.

Used only for local services such as VHF band stereo (received as mono on the AR-ONE)

and UHF TV sound channels.

LSB Lower Side Band is form of SSB (Single Side Band). LSB tends not to be used

commercially but is extensively used by Radio Amateurs on frequencies below 10 MHz.

This assists the separation of Commercial and Amateur users on traditionally shared bands

and prevents them from speaking to each other.

SSB is a very efficient method of transmission as the unwanted second sideband and

carrier

have been removed. This allows the full transmitter power to be employed in carrying

useful information within the wanted sideband. As a result, greater distances are possible

on

SSB and a smaller frequency bandwidth is required than most other modes.

USB Upper Side Band The same comments apply as for LSB. By convention, Radio

Amateurs also use USB above 10 MHz.

CW - Continuous Wave Often referred as Carrier Wave or Morse Code. Commonly

used

on the short wave bands by radio amateurs toward the lower end of each band allocation.

Some commercial use is still made by shipping etc although its use is being phased out

due

to the introduction of automated stations.

23

For above reasons it is necessary to alter the STEPsize according to local bandplan

conventions. The AR-ONE has been pre-programmed at the factory with all the bandplan

data (specific to each market area) so that the AR-ONE will automatically select theappropriate step size and mode for the frequency chosen. This greatly simplifies operation

of the receiver while you are familiarizing yourself with all functions.

The pre-programming of step size may be manually over-ridden so you may choose

alternative settings at will or when band plan are updated.

Should you wish to change the default tuning step size, push the FUNCkey and then push

the VFO key.

The third row of the LCD will display the current default size.

The bottom line of the LCD displays the icon STEP SET to indicate that the AR-ONE is

waiting you to change the step size.

Use the main tuning dial or arrow key to select the desired step size. To accept the

displayed

tuning step size, push the ENT key.

The tuning step size may also programmed in 1 Hz (via the keypad) so that unusual step

sizes other than stated are possible. The acceptable step size range is less than 1 MHz in

air. However, it is not simply a case of using the narrowest filter at all times, particular

modes

require differing amounts of bandwidth in order to operate otherwise the receive systemsimply will not produce intelligible sound.

Correct receive mode and IF bandwidth must always be selected for optimum reception. If

the bandwidth selection is too narrow, distortion or signal break-up may occur. If the

bandwidth selection is too wide, adjacent interference may be encountered.

For this reason, a selection of IF filter bandwidths are fitted as standard. Typical examples

of

receive mode and IF bandwidth are:

300 KHz -- VHF FM broadcast (220 KHz may be also be used mono only)

200 KHz -- VHF FM broadcast (110 KHz may be also be used mono only)

100 KHz or 30 KHz Wireless mic, etc. (30 KHz for satellite FAX, too)

16 KHz PMR, amateur band, etc. FM 6 KHz may also be used

8.5 KHz or 6 KHz VHF/UHF airband, short wave broadcast, medium & long wave, PMR,

etc.

3 KHz Short wave amateur band, short wave utility such as oceanic airband etc.

0.5 KHz Morse code used by radio amateurs and some marine traffic on short wave

An appropriate IF filter is automatically selected when automode is engaged. However any

combination of IF filter and receive mode is possible in the manual mode. When you have

manually selected an IF filter bandwidth, automode will be disengaged, but the receive

mode, step size, etc will be retained until they are changed manually.

2-7-1 Manually selecting IF bandwidth

Push the FUNC key, and then push the MODE key.

2-11 OFFSET

This function enables receive frequency to be quickly SHIFTED by a predetermined values,

this makes it easy to track duplex-transmissions or check repeater inputs/outputs. Offset

frequencies may be factory pre-programmed into the auto-mode band plan data for some

world market areas. Frequency offset may also be programmed manually.

The locations for frequency offset storage are numbered 00 to 47 with 00 acting as OFF,

this

makes 47 locations available.

Frequency offset may be programmed into VFO, memory channel and search banks. It is

most convenient to set-up in VFO mode then save the data to specific memory channels

for quick recall at a later date. Frequency offset is primarily designed for memory channel


29/84

use, it may appear rather long winged to toggle on/off in VFO mode. However even when

programmed, frequency offset is in no way detrimental to normal operation.

The acceptable range of frequency offset is 0 MHz to 999.999 MHz, of course if the offset is

set to 0 MHz, the frequency will not change! Before the FREQUENCY OFFSET function

can

be used, it first needs to be configured (unless factory programmed for certain bands).

3 Memory channels & banksIt is convenient to store commonly used frequencies into a memory channel along with

mode etc, this saves having to key the data in over and over again. Memory read is very

straightforward and quick when compared to retyping all data.

3-1 Memory channel overview

Think of memory channels as pages in a notebook each of which is numbered to identify it.

Data may be written to each new page (memory channel) and each page may be

overwritten with new data, they can be used over and over again. The AR-ONE has 1,000

memory channelsand a priority channel.

Each memory channel may hold:

One receive frequency

Receive mode

Tuning step

Frequency offset

Attenuator setting

Text comment of up to 12 characters

The alphanumeric comment may be used to ease identification at a later date and to

provide

text search function. The 1,000 memory channels are divided into 10 banks, each having

100 channels. The memory banks are identified by the first BANKnumber 0, 1, 2, 3, 4, 5,

6.

7, 8 and 9 and the individual channels are numbered from 00 to 99.


31/84

30

Examples are 000 for the first channel location in memory bank 0 and 099 for the last

memory channel in memory bank 0.

415 is the location: memory bank 4 channel 15.

The data contents of memory and search banks are held in a EEPROM so that no backup

battery is required for memory retention.

The stored data may be quickly and easily recalled, changed or deleted using the memory

recall and delete functions.

Note: When the receiver is switched OFF, all VFO data will be automatically stored into

EEPROM memory storage.

4 SCAN scanning memory channelsThe AR-ONE has a SCAN mode whereby the contents stored in the MEMORY

CHANNELS

ARE AUTOMATICALLY RECALLED AND MONITORED very quickly for activity

scanned.

*** It is important that you do not confuse SCANand SEARCHmodes. ***


35/84

34

SEARCHmode (covered later in this manual) automatically TUNES THE RECEIVER

THROUGH ALL FREQUENCIESbetween two specified frequency limits looking for activefrequencies.

4-1 SCAN outline introduction

During SCAN, the AR-ONE automatically recalls memory channel which contains data in

numeric order and monitors it looking for activity. When an active memory channel is

located (when a signal is found and the squelch is open), the AR-ONE will temporarily stop

scanning.

4-2 Starting SCAN

Presuming that some memory channels are programmed with data, to start the scan

process will take one push of the SCANkey.

The icon HYPER CAN is displayed on the LCD to indicate that the SCAN process has

been started, a bank number will be also be displayed representing the current bank.

Ensure that the squelch is set to threshold point so that background noise is

cancelled and the squelch closes (otherwise scan will not operate).

When SCAN has been selected, only the currently displayed memory bank WHICH

CONTAINS DATA will be SCANNED, receive mode and frequency are unimportant. Any

memory channels which contain no data (empty) will be ignored (skipped).

4-3 Selecting a scan bank

The memory bank identifier (such as 3) will be displayed on the middle right of the LCD.

If more than one memory channel is programmed into the current memory bank, and when

an active channel has been located (busy, so the squelch opens), the scan process will

temporarily pause on the active channel, the memory location (such as 115) will be

displayed along with any accompanying text (displayed underneath the memory location).

To select another memory bank for scanning, use the right arrow key or left arrow key.

If no data is available, the next bank with valid data will be recalled (empty memory banks

are skipped).

delay parameters.

2.0s The AR-ONE will wait the specified time after the squelch closes before

resuming scan or search.

HOLD The AR-ONE will stop indefinitely when an active frequency is located, this

is very useful when you dont want to miss that once-in-a-lifetime

transmission!

OFF The AR-ONE will resume scan or search instantaneously when the

squelch closes.



Or, push the down arrow keyto move to the next item on the configuration menu (FREE).

6-11 Configure FREE (Scan free and Search free)

The scan free and search free parameter determines how long the AR-ONE will remain on

activefrequency before resuming scan or search even though the frequency is still active.

This is useful if you wish to gain a snap shot of activity without the AR-ONE being tied to a

busy frequency for long periods of time (such as when monitoring active commercial

repeaters etc). Scan free and search free time saves you having to manually intervene to

force the scan or search process to resume and saves the need to lockout memory

channels or search frequencies using the PASSfunction. The limits are OFF and 0.1 to 9.9

seconds. The default setting is OFF.

6-13 Configure audio filters (HPF / LPF)The AR-ONE is equipped with an audio HPF (High Pass Filter) and a LPF (Low Pass

Filter).

6-13-1 Configure audio HPF (high pass filter)

The audio high pass filter is useful for limiting the audio bass response (allowing higher

tones to pass) improving intelligibility in certain circumstances (such as low frequency

whistles on AM, SSB & CW).


60/84

59

There are four available pass frequencies: 50Hz, 200Hz, 300Hz, and 400Hz.

The higher the frequency the more limited the audio bandwidth. For highest fidelity forlistening, select 50Hz. The filter selection can be set to automode to select the proper filter

setting automatically.

The default is AUTO.


Push the down arrow key to move the cursor to HPF selection point.

This menu is to configure the high pass filter.

Or, push the down arrow keyto move to the next item on the configuration menu (LPF).

6-13-2 Configure audio LPF (low pass filter)

The audio low pass filter is useful to cut off high tones (allowing low tones to pass) to

improve intelligibility of weak signals in close proximity to adjacent interference and to

remove hissmaking listening for extended periods easier on the ears.

There are four available pass frequencies: 3KHz, 4KHz, 6KHz and 12KHz.

The lower the frequency the more limited the audio bandwidth. For highest fidelity for

listening, select 12.0KHz. The filter selection can be set to automode to select the proper

filter setting automatically.



Push the down arrow key to move the cursor to LPF selection point.

(De-Emphasis).

6-14 Configure Audio De-emphasis

This is really only applicable to FM mode and affects the sharpnessof recovered audio.


62/84

61

The FM transmission in different world areas have been different defaults for de-emphasis.

For example, a value of 759 is selected in Europe, the recovered audio will sound verymuffled.

The available range is as follows: THRU, 25uS, 50uS, 75uS, and 750uS

The audio de-emphasis can be set to automode to select the proper setting automatically.

(PRIO-CH).

6-15 Configure PRIO-CH (Priority Channel)

The priority function enables you to carry on scanning, searching or monitoring while the

AR-ONE checks a selected frequency for activity (taken from one of the 1,000 memory

channels periodically).

The priority checking is accomplished by momentarily tuning the receive circuit to the

priority

frequency to see if it is active. If the activity is found, the AR-ONE will remain on the active

frequency until the signal disappears. If no activity is detected, the receiver returns to the

VFO frequency, scan channel or search bank from where it originated.

The priority function has a large number of applications and is particularly useful for


63/84

62

keeping

an eye on a distress frequency while scanning or searching another frequency band.

Note: Depending upon the frequency and mode stored as priority, an audibleclick may be

heard when the priority function is in operation. This is quite normal and is caused by the

internal switching of circuitry necessary to accomplish the frequency change (as two

frequencies cannot simultaneously be monitored).

6-15-1 Engaging Priority channel

Once engaged, the frequency is checked for activity periodically by the preset period that is

set by the configuration menu.

To engage the priority function, push the FUNCkey and then push the 7key.

Push the down arrow key to move the cursor to PRIO-CH selection point.

The function enables you to tap the 2nd

IF signal (10.7MHz) or the 3rd

IF signal (455KHz)

from the BNC (marked as 10.7MHz) type connector on the rear panel. The 10.7MHz of the

2nd

IF signal is to be used with an optional SDU5500 or SDU5600 spectrum display unit for

signal analysis. The bandwidth at 10.7 MHz is +/- 5 MHz from the center frequency (10

MHz total).

6-16-1 Selecting IF output frequency

To engage the priority function, push the FUNCkey and then push the 7key.

Push the down arrow key to move the cursor to IF out SEL selection point.

The function enables you to select the reference signal of the receiver.

The AR-ONE has built-in a stable reference oscillator, however, an external high stability 10

MHz reference (such as off-air atomic coupled) can be accepted from the SMA connector(marked as 10 MHz IN) on the rear panel of the AR-ONE.

Push the down arrow key to move the cursor to REF SEL selection point.


reference signal source (internal or external). The default is INT.



This completes the configuration settings.

7 Computer control

Connect the AR-ONE to one of the serial port of a computer using an RS-232C cable

terminated in a 9-pin plug.

The RS-232C parameters may be defined using the OCNFIGURATION menu. Baud rates

(data transfer speed) may be set to 4800 or 9600 bps. It is also possible to set an address

to facilitate connection of up to 99 AR-ONE to a single port for custom operation, the

addresses may be set between the limits of 01 to 99 with 00 representing single radio

operation.

7-1 How to send an RS-232C command

Each command comprises of two upper case letters (header) along with operations as

required. All command use ASCII code which MUST BE IN UPPER CASE(except for the

up

arrow key, down arrow key, right arrow key, left arrow key and remote ID command (^A)

which are non-printable and use the control codes of ASCII). A terminal program running

on

a computer should be set to:

Baud rate: 4800 or 9600 bps (this should match the AR-ONE)

DATA BIT: 8

STOP BIT: 2


66/84

65

PARITY: NONE

XFLOW: ONE

A multiple command entry is only valid where specified. Where a multiple command entry is

allowed, each command MUST be separated with a space h20 (HEX DECIMAL). Each

command is completed and a [CR] or [CR][LF]. Although there is no local echo, either [CR]

or specified response should come back from the receiver after confirming the correct

command. If no response has been gained after a short while, the receiver has failed to

receive the command properly. Send a [CR] then re-send the command. Should problem

persist, check your connections and try reducing the RS-232C baud rate.

7-2 Power on the AR-ONE
